  1. Nice cover for military radar - Celldar by AHuxley · · Score: 0, Troll · on Rain Drops Signal Cell Phones
    Meteorological services or cover for a fun new military radar set?
    Google for cell phone radar ppl eg. Celldar
    Cheap, always on, very hard to kill, nice world wide exports.
    If it is targeted, you have the best PR ever?

  2. Re:Serves up webpages... by numbski · · Score: -1, Offtopic · on Hand-made Web Server, Built From 200 TTL Chips

    Dunno.

    This is PRECISELY the type of article that I keep pushing to get interest in a Slash-torrent extension going. I didn't even bother to click the link in the article.

    You just *know* it is gonna get pummelled to hell and back. It happens at least once a month too. Someone decides to run a webserver on his toaster, and the next thing you know we've burned down a full square blocks worth of homes.

    All of that could be avoided if we could get a person or two that is skilled in extension coding to take up the cause. I've done a little reading so far, but if I tried to do it myself I would make a mess of it because it would try to pull a perl backend.

    That's right kids, you have to install ActivePerl to run my extension. Have a nice day! :) (or get people to chip in the cash to buy me a perl compiler. bleh)

    Would it be stored in an ASIC ? :)

  4. Re:Directional Antennae by DGolden · · Score: 1 · on Revising Spectrum Rules

    Many car radio systems already use "magic" directional phased array receiving antennae to keep your radio signal of choice consistent.

    But the really shiny stuff is with the usual military-industrial-complex crowd - For example, Roke's Agile Phased Array Antennae, designed for 7-8 GHz satellite communications to and from moving vehicles. On your own head be it if you choose to visit that link. Roke can be... scary... and might study their http access logs a little more closely than most...

    You can also google for similar terms for similar Japanese projects.

    So the technology is advancing pretty fast.

  5. You've missed the point by kingk0ng · · Score: 5, Informative · on Tracking People Via Cell Phone

    This isn't just monitoring which cell a phone user is in, but actually using the base station masts as radar to detect moving objects (e.g. people and cars) anywhere within the field - which means basically making the entire UK transparent, even if you're not carrying a cellphone! It's perfectly serious, here's a link to the company developing it - first mentioned in Jane's Defence Weekly in 2000, but it's only recently got government funding.

  6. Celldar by masterkool · · Score: 2, Informative · on Mobile Telephone Mast Signals Usable As Radar

    Here is the CELLDAR teaming site for BAE Systems and Roke Maynor Research and here is the official BAE systems news about CELLDAR.

    There was some discussion last summer of how this technique might be used in conjuction with mobile phone transmitters to detect stealth aircraft.

  8. Re:Oh for the love of God! by Beliskner · · Score: 1 · on Spark Gaps and Ultra Wide Band Data Transmission
    Why don't you get your hand off your dick for 5 minutes and look for some info on EM transmitters.
    After you... Don't want a sticky keyboard, eh? I thought so.
    I like petting kittens.
    I don't want you to get my cat sticky either.
    Do you honestly believe that the same device could transmit frequencies across the ENTIRE FUCKING EM SPECTRUM?!
    I thought that was the "miracle discovery", ah well I guess it's ultrawideband << totalband instead of merely ultrawideband < totalband. The military is already looking into this stuff, apparently it can see through walls and the ground.

    Both narrowband and UWB can be harmful against lots of stuff, quoting US military sources,

    an official from the U.S. Army's Space and Missile Defense Command stated that recent scientific advances in radio frequency (RF) weapons technology by several states raise significant concerns. Broadly speaking, these weapons use high power microwave energy, in either narrow or wideband form, to disrupt or destroy the high-density metal oxide semiconductor devices that are used in modern computers and sensors.....

    Current technology has produced a 25-gigawatt ultra-wideband source, a 100-gigawatt UWB device is anticipated within a year, and finally, travelling wave devices are also being explored for UWB applications
    A 100 Gigawatt UWB pulse is.... Not gonna be good for my sperm count. How does it sound to you? Oh yeah, it's transient so are you volunteering? Looks like lots of research is being done below 6GHz, hmmm that frequency spread should be mmmmmkay. This link has the real nitty gritty, symbol rates and all that. Can someone gimme my PhD already?
